About this 3D model

Inspired by the Noctua NA-IS1 spacer, this fan spacer creates a gap between your computer's case fan and the side panel / radiator. This gap reduces turbulence in airflow for higher performance and lower noise levels. This was designed with the largest center hole possible to accommodate any type of fan and at 5mm thick provides the best results. Designed for both 120mm and 140mm fans, as well as a 2.5mm thick option for 120mm fans for limited space applications. - If you are experiencing lift on the first few layers around the sides, try adding an inside our outside brim to help with adhesion.
